J. J. Sanders, the Parole Clerk of Arizona State Prison, surveyed prisoner-mail policies in state prisons across the U.S. about late 1912. Sanders vigorously sought to bring such policies to public attention. Those efforts included publishing two pamphlets entitled Prison Reform (1913) and Prisoners’ Mail (1914).
